Water is added again to the mud-like layer which remains in the washing tank 3 again to make it slurry, then it is fed to a decomposition tank 5, and sulfuric acid is injected therein to decompose the remaining fly ash component. A liquid, which overflows the decomposition tank 5, flows into a growth tank 6 to form crystals of a solid phase therein, and a liquid, which overflows the growth tank 7, flows into a separation tank 6 to separate materials with high settling velocity from the slurry liquid.  Aqueous solutions having different concentrations discharged by a solid-liquid separator 8 or the like are stored in a circulating liquid tank 10, a part of the stored solution is moved to the washing tank 3 to dissolve water-soluble materials in the fly ash, then it is discharged to a filtration and circulation tank 12 outside a circulatory system of a main liquid, and the remainder of the solution is reused as water for slurry.

Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity for a counter by utilizing a microcomputer by determining the connection time measured up to the time when frequency at which ion current is below a predetermined current value exceeds a predetermined frequency as combustion time. SOLUTION: A power supply 24 for bias applies a high voltage to a spark plug 18 through a high voltage diode 23 so that ion current is generated in a combustion chamber 10 after the ignition. An electronic controller 6 compensates basic injection time in accordance with an operation condition of an engine 100, determines final electricity conducting time of an injector, and controls a fuel injection valve 5. Moreover, ion current is generated in the combustion chamber 10 per ignition to measure combustion time based on the connection time until the ion current disappears. A frequency at which the ion current is below a predetermined current value is detected. When the detected frequency exceeds a predetermined frequency, the connection time measured till the time is used as combustion time.  Consequently, a counter becomes unnecessary by utilizing a microcomputer, and the manufacturing cost can be reduced.
